I had visited this place which is a backwater in the Fontainebleau forest in March 2014. Since then, I had the desire to return. And a carrot was the soght of the famous blue form syngrapha of Polyommatus coridon. In this species apart from very rare cases, they are brown. But a blue forms exist in Corsica if I do not mistake. Syngrapha is different.



It was decided that on July 18 we must go back. Chanfroy But when we do have the train and the bike is a test. 12km to go mainly flat and mounted. And the road to Chanfroy Milly is torture. Aka Sand embourbeur the bike. Next is the uphill road the last bastion that stands against my desire to Syngrapha. A positive return is only downhill. Chanfroy does not offer his treasure on a tray.



10:15 after refueling at the corner supermarket. It's time. My legs are struggling, but I can not give up, the sudden 2013 damage is still there. A small express stop in place before because my college wanted to go to a specific place before going to Chanfroy. Having forgotten the plan and are not shown immediate U-turn. Lost enough time Chanfroy it's now or never!



Some pictures of the place, it also puts an end to rumors. The Piochon in summer it works too. This is what I found after taking off a piece of oak bark. A beautiful young intricatus probably because very soft to the touch.


Carabus intricatus


Pyronia tithonus and Aphantopus hyperantus

Then we get on the path that mèneras us Chanfroy curious black catches my attention ... + damage from drought or heat wave controlled fire? The bitter smell of burning still felt very strong. Only this burnt heather zone. Pine trees all around that seemed well are not yellowed. But I find the time to the limit of unconsciousness to light a controlled fire. Pine burns very quickly and very well. I doubt that here in time that was not an exception.



We arrive at a first open area. It is above Chanfroy and offers a glimpse of what we can find. Some sylvandres, coridons of some half-mourning, and Pierides aricias. Buprestis novemaculata of flight also attracted to a completely toasted pine. But the exhaustion of the journey that I could not catch.




Polyommatus coridon male


Hipparchia fagi male and female. You should know that is not found Hipparchia Genava and alcyone in the Fontainebleau forest. Or examination of Jullien bodies is imperative to differentiate between these 3 species


Chanfroy is finally (reached by the northern zone / is), but the poor is confirmed year ago little or even Cicindela hybrida very abundant in 2014 are virtually absent. Lunch is recovering forces that later. A tragedy is played out before our eyes Alexis explain to you. But eventually a move that few people dare to do.



In the end we went around. I'm seeking careers in one place shot IDF or wildlife is present. This place still eludes me. Few butterflies but some interesting catches. Absentee not flambé no Everes however agiades or Lasiommata Maera yet identified. And probably others. Bad year? Heatwave? Precocity? Chance? I could never explain



Polyommatus coridon male.

At 14:30 unfortunately time has come to turn back. Despite several female Polyommatus coridon well labeled with a maroon lapels. Syngrapha it is not today. But this is only a postponement. I want to finish a poor year catches a small rarity.
Chanfroy is good but not worth Montigny sur Loing in terms of diversity.

For species

-Leptidea Sinapis

-Pieris (Both since some had visible veins and some not)

-Plebejus Argus (first time I've seen on the land and not the coast). But if I excluded Chanfroy heather lot like the Vendée dunes.

-Cupido Sp (probably minimus saw its dwarf size!)

-Polyommatus Coridon (second most abundant species)

-Polyommatus Icarus (one icarinus shape! Not nabbed yet I have put in freedom because I doubted serious error> <)

-Aricia Agestis

-Pyronia Tithonus

-Hipparchia Fagi

-Melanargia Galathea (new specimens curiously but very sporadic and sparse we arrive late for him)

-Argynis Paphia

-Ochlodes Sylvanus (I doubt though some had almost white snow tasks but the right wing milieu missing each time)

-A Zygène

-Aphantopus Hyperantus (it is the same in such a dry area Chanfroy!)

And the classic Pararge aegeria.

Here I think I made the turn.

Good hunting to all

Thanks a lot for this interesting report Axel.

Form syngrapha is common in Chanfroy, about 10% of the females. The best timing in normal years is middle August for coridon, there you will see plenty of females.

In Chanfroy, I have personally seen 45 species with about 22 species in July. And there must be more as I am not an expert of Hesperiidae and almost ignore them. There are also some known species from there that I have never met like Hipparchia statilinus. I guess Nymphalis polychloros is also there.

I guess 2015 won't be a good year for summer species (too hot, too dry). On your pictures, it looks totally dried out.

Here are the list of the species I have seen in Chanfroy with date and temperatures, it may interest you.

There are other Chanfroy experts on this forum, plebejus, xavm (Xavier), cormion, who may give you other interesting insights.

And a special recto form syngrapha verso aberration arcuata I caught in Chanfroy to illustrate.

One month to the day after I did not want to stay on a defeat. It was decided I had to go back for them but also see Hipparchia statilinius of Fontainebleau.

Damage to this female (and poor image quality) but in the end I captured both in the minutes that follow. No aberrant wollastoni like you but I did settle for. Not difficult to identify the reverse is identical to normal females.



Later near the monuments of those shot in the center of the plain. Without doubt the most northerly Hipparchia statilinius.
